Description

[0001] Cosmetic preparation against acne

[0002] The present invention relates to a cosmetic product comprising a packaging medium with two spatially separated chambers, wherein the first chamber contains a lyophyllisate of bacteria of the strains C. acnes 6609 (H1), C1, C3, D1, A5, H1, H2, H3, K1, K2, K4, K6, K8, K9, L1 and / or F4, and the second chamber contains a water-containing cosmetic

[0003] The preparation contains a method for treating acne with this preparation.

[0004] The desire to look beautiful and attractive is rooted in human nature. Even though the ideal of beauty has changed over time, the pursuit of a flawless appearance has always been a human goal, as a pleasing appearance boosts self-esteem and attractiveness to others. The condition and appearance of the skin plays a significant role in achieving a beautiful and attractive appearance.

[0005] In oily and impure skin, which is considered the transitional state between healthy, normal skin and pathologically altered acne-prone skin, the skin produces increased amounts of sebum (seborrhea). This serves as an ideal breeding ground for numerous microorganisms, especially Propionibacterium acnes (nowadays referred to as Cutibacterium acnes, C. acnes, which is why the new abbreviation C. acnes is used instead of P. acnes in this disclosure) and Pityrosporum species.

[0006] Microorganisms decompose sebum into glycerol and fatty acids, stimulating the sebaceous glands to increased production and attacking and destroying the follicle walls in the skin. This causes inflammation in the skin (pimples, pustules, nodules, cysts), which often heal only with scarring, thus permanently damaging the appearance of people suffering from impure skin (W. Umbach [ed.], Cosmetics, Development, Production and Application of Cosmetic Products, 2nd ed. Thieme Verlag, Stuttgart, 1995).

[0007] Acne (in the narrower sense, acne vulgaris) refers to various diseases of the sebaceous gland follicles, which are caused by secretion and keratinization disorders, resulting in the following

[0008] Acne vulgaris is characterized by inflammation and possible scarring. It occurs mainly during puberty and is usually concentrated on areas of skin rich in sebaceous glands (face, neck, chest, back). Sebaceous gland hyperplasia and a keratinization disorder of the follicles lead to blockage, resulting in the formation of comedones and the characteristic lesions of acne vulgaris (Pschyrembel, Clinical Dictionary, 258th edition, Walter de Gruyter Publishing House, Berlin, 1998).

[0009] Conventional products for treating oily and / or impure skin, as well as acne-prone skin, usually have the disadvantage of stressing and drying out the skin and providing little nourishment.

[0010] Furthermore, highly acidic (pH values ​​below pH 4.0) and strongly oxidizing agents (e.g., benzoyl peroxide) are used in the treatment of acne, which

[0011] Stress the skin's acid mantle and attack or burn the skin.

[0012] It was therefore an object of the present invention to develop a significantly milder and more nourishing cosmetic and / or dermatological preparation for the treatment of oily and impure skin, as well as for the treatment of acne (and in particular acne vulgaris), than those known from the prior art. Furthermore, it was an object of the present invention to develop a cosmetic and / or dermatological preparation for the treatment of acne (and in particular acne vulgaris) that is effective at a skin-friendly pH (pH greater than 4.0), does not corrode the skin, and places only a minimal burden on the skin's acid mantle. Preparations were also to be developed that, at a skin-friendly pH (pH greater than 4.0),

[0013] The growth and spread of acne-causing bacteria on the skin

[0014] suppress. Furthermore, these preparations should significantly reduce the concentration of acne-causing bacteria on the skin and in the sebaceous glands.

[0015] The problems are surprisingly solved by a cosmetic product consisting of a packaging material with two spatially separated chambers, wherein the first chamber contains a lyophyllisate of bacteria of the strains C. acnes 6609 (H 1 ), C1 , C3, D1 , A5, H 1 , H2 , H3, K1 , K2, K4, K6, K8, K9, L1 and / or F4 and the second chamber contains water

[0016] Contains a cosmetic preparation.

[0017] The lyophyllisate can be obtained from bacteria of strains C. acnes 6609 (H1), C1, C3, D1, A5, H1, H2, H3, K1, K2, K4, K6, K8, K9, L1 and / or F4 according to one of the conventional methods.

[0018] Prior art methods for the lyophilization of bacteria (for example, with the addition of dextran and / or glycerin) can be prepared and are described in standard works on pharmaceutical technology. While the prior art includes WO 2016 / 172196 and WO 2018 / 073651, which also disclose the C. acnes strains according to the invention, these documents did not provide a path to the present invention because, among other things, they do not disclose the medium with which the C. acnes bacteria can be activated in sufficient quantities. Although WO 2016 / 172196 mentions the fundamental possibility of using

[0019] The use of freeze-dried bacteria was noted, but the expert found it extremely difficult to reactivate them on the skin in medically safe yet effective quantities within a short time. It is also not disclosed how the bacteria can be applied to the affected skin areas in a targeted and uniform (homogeneous) concentration in a way that is easy for laypersons to handle, as not every cosmetic product is a suitable carrier. Phase separations,

[0020] Agglomeration, separation from the preparation, and viscosity changes are typical problems that occur when incorporating lyophilisates. Furthermore, virtually all cosmetics contain ingredients intended to protect them from microbial degradation, so it could be assumed that in a simple combination of cosmetic preparation and bacteria, the latter would be more or less completely killed by the preservative components of the cosmetic preparation.

[0021] The first chamber may contain cosmetic materials in addition to the lyophyllisate from bacteria.

[0022] The product contains components such as oils and / or thickeners. It may also be advantageous, as proposed in WO 2018 / 073651, to add peptone and / or hydroxyethylcellulose according to the invention.

[0023] According to the invention, it is preferred to use the C. acnes strains C3 and / or K8.

[0024] According to the invention, the combination of both strains in equal proportions is particularly preferred.

[0025] According to the invention, it is particularly preferred to combine these strains (i.e. C3 and / or K8) with C. acnes strains A5 and / or F4.

[0026] According to the invention, it is advantageous if the cosmetic preparation in the second chamber has a pH value of 4 to 8.

[0027] To give the product according to the invention the correct consistency for its application, it is advantageous according to the invention if the cosmetic preparation in the second chamber contains one or more thickening agents. It is particularly advantageous within the meaning of the present invention if the cosmetic preparation in the second chamber has a viscosity of at least 500 mPas. According to the invention, the viscosities are measured using the Rheomat R 123 instrument with spindle measuring body 1 and a constant rotational speed of 62.5 rpm at a temperature of 25°C.

[0028] According to the invention, it is preferred if the cosmetic preparation in the second chamber contains carrageenan and / or polyacrylic acid. The term "carrageenan" encompasses...

[0056] According to the invention, the cosmetic preparation in the second chamber can preferably be in two forms:

[0057] The first form is characterized in that the cosmetic preparation in the second chamber is in the form of an aqueous preparation. In this embodiment, it is preferred according to the invention if the preparation is in the form of a gel. The second form is characterized in that the cosmetic preparation in the second chamber is in the form of an oil-in-water emulsion.

[0058] In this case, according to the invention, it is advantageous if the cosmetic preparation in the second chamber contains glyceryl stearate citrate, cetearyl alcohol, sodium cetearyl sulfate,
